10 Getting Started Guide

Switch Ports

The N2024/N2024P front panel provides 24 Gigabit Ethernet

(10/100/1000BASE-T) RJ-45 ports that support auto-negotiation for speed,

flow control, and duplex. The N2024/N2024P models support two SFP+ 10G

ports. Dell-qualified SFP+ transceivers are sold separately.

The N2048/N2048P front panel provides 48 Gigabit Ethernet (10BASE-T,

100BASE-TX, 1000BASE-T) RJ-45 ports that support auto-negotiation for

speed, flow control, and duplex. The N2048/N2048P support two SFP+ 10G

ports. Dell-qualified SFP+ transceivers are sold separately.

The front-panel switch ports have the following characteristics:

• The switch automatically detects the difference between crossed and

straight-through cables on RJ-45 ports and automatically chooses the MDI

or MDIX configuration to match the other end.

• SFP ports support Dell-qualified transceivers.

• RJ-45 ports support full-duplex mode 10/100/1000 Mbps speeds on

standard Category 5 UTP cable.

• SFP+ ports support SFP+ transceivers and SFP+ copper twin-ax

technology plus SFP transceivers operating at 1G.

• The N2024P/N2048P front panel ports support PoE (15.4W) and PoE+

(30W).

Console Port

The console port provides serial communication capabilities, which allows

communication using RS-232 protocol. The serial port provides a direct

connection to the switch and allows access to the CLI from a console

terminal connected to the port through the provided serial cable (with RJ45

YOST to female DB-9 connectors).

The console port is separately configurable and can be run as an asynchronous

link from 1200 baud to 115,200 baud.

The Dell CLI only supports changing the speed. The defaults are 9600 baud

rate, 8 data bits, No Parity, 1 Stop Bit, No Flow Control.

Getting Started Guide 11

USB Port

The Type-A, female USB port supports a USB 2.0-compliant flash memory

drive. The Dell Networking switch can read or write to a flash drive formatted

as FAT-32. You can use a USB flash drive to copy switch configuration files

and images between the USB flash drive and the switch. You can also use the

USB flash drive to move and copy configuration files and images from one

switch to other switches in the network.

The USB port does not support any other type of USB device.

Reset Button

The reset button is accessed through the pinhole and allows you to perform a

hard reset on the switch. To use the reset button, insert an unbent paper clip

or similar tool into the pinhole. When the switch completes the boot process

after the reset, it resumes operation with the most recently saved

configuration. Any changes made to the running configuration that were not

saved to the startup configuration prior to the reset are lost.

Port and System LEDs

The front panel contains light emitting diodes (LEDs) that indicate the

status of port links, power supplies, fans, stacking, and the overall system

status.

For information about the status that the LEDs indicate, see the User’s

Configuration Guide.

Stack Master LED and Stack Number Display

When a switch within a stack is the master unit, the stack master LED, which

is labeled M, is solid green. If the M LED is off, the stack member is not the

master unit. The Stack No. panel displays the unit number for the stack

member. If a switch is not part of a stack (in other words, it is a stack of one

switch), the M LED is illuminated, and the unit number is displayed.

or placed on a flat surface.

Make sure that the chosen installation location meets the following site

requirements:

•

Power

— The switch is installed near an easily accessible 100–240 VAC,

50–60 Hz outlet.

•

Clearance

— There is adequate front and rear clearance for operator

access. Allow clearance for cabling, power connections, and ventilation.

•

Cabling

— The cabling is routed to avoid sources of electrical noise such

as radio transmitters, broadcast amplifiers, power lines, and fluorescent

lighting fixtures.

•

Ambient Temperature

— The ambient switch operating temperature

range is 0 to 45ºC (32 to 113ºF) at a relative humidity of up to 95 percent,

non-condensing.

NOTE: Decrease the maximum temperature by 1°C (1.8°F) per 300 m (985 ft.) above

900m (2955 ft.).

•

• One rack-mount kit (N20xx) for rack installation, two mounting brackets,

bolts, and cage nuts

• One set of self-adhesive rubber pads for the free-standing switch (four pads

are included)

Unpacking Steps

NOTE: Before unpacking the switch, inspect the container and immediately report

any evidence of damage.

Place the container on a clean, flat surface and cut all straps securing the

container.

Open the container or remove the container top.

Carefully remove the switch from the container and place it on a secure

and clean surface.

Remove all packing material.

Inspect the product and accessories for damage.

Rack Mounting a N20xx Switch

WARNING: Read the safety information in the Safety and Regulatory Information

as well as the safety information for other switches that connect to or support the

switch.

The AC power connector is on the back panel of the switch.

Installing in a Rack

WARNING: Do not use rack mounting kits to suspend the switch from under a

table or desk, or attach it to a wall.

16 Getting Started Guide

CAUTION: Disconnect all cables from the switch before continuing. Remove all

self-adhesive pads from the underside of the switch, if they have been attached.

CAUTION: When mounting multiple switches into a rack, mount the switches

from the bottom up.

Place the supplied rack-mounting bracket on one side of the switch,

ensuring that the mounting holes on the switch line up to the mounting

holes in the rack-mounting bracket. Figure 1-7 illustrates where to mount

the brackets.

Figure 1-7. Attaching the Brackets

Insert the supplied bolts into the rack-mounting holes and tighten with a

screwdriver.

Repeat the process for the rack-mounting bracket on the other side of the

switch.

Insert the switch into the 48.26 cm (19 inch) rack, ensuring that the rack-

mounting holes on the switch line up to the mounting holes in the rack.

Secure the switch to the rack with either the rack bolts or cage nuts and

cage-nut bolts with washers (depending on the kind of rack you have).

Fasten the bolts on bottom before fastening the bolts on top.

CAUTION: Make sure that the supplied rack bolts fit the pre-threaded holes in the

rack.

NOTE: Make sure that the ventilation holes are not obstructed.

Getting Started Guide 17

Installing as a Free-standing Switch

NOTE: We strongly recommend mounting the switch in a rack.

Install the switch on a flat surface if you are not installing it in a rack. The

surface must be able to support the weight of the switch and the switch

cables. The switch is supplied with four self-adhesive rubber pads.

Attach the self-adhesive rubber pads on each location marked on the

bottom of the switch.

Set the switch on a flat surface, and make sure that it has proper

ventilation by leaving 5 cm (2 inches) on each side and 13 cm (5 inches) at

the back.

Stacking Multiple N20xx Switches

You can stack N20xx switches up to 12 switches high using the mini-SAS

ports located on the rear of the switch. N20xx switches support stacking only

with other N20xx series switches. When multiple switches are connected

together through the stack ports, they operate as a single unit with up to 576

front panel ports. The stack operates and is managed as a single entity.

NOTE: If you are installing a stack of switches, you need to assemble and cable the

stack before powering up and configuring it. When a stack is powered up for the

first time, the switches elect a Master Switch, which may occupy any location in

the stack. The Master LED on the front panel is illuminated on the master unit.

Creating a Switch Stack

Create a stack by connecting adjacent units using the mini-SAS stacking

ports on the back panel of the switch. Figure 1-8 on page 18 shows the

switches connected in a ring topology, which is the recommended topology

for a stack.

Connect one of the mini-SAS cables into either of the stacking ports of the

top switch and the switch directly below it.

If necessary, use a separately purchased, longer (1 meter or 3 meter) mini-

SAS cable to connect the switches.

Repeat this process until all of the devices are connected.

Use the remaining stacking cable to connect the two remaining stacking

ports together so that a ring topology is assembled.

18 Getting Started Guide

Figure 1-8. Connecting a Stack of Switches

The stack in Figure 1-8 is connected in a ring topology and has the following

physical connections between the switches:

• The bottom mini-SAS port on Unit 1 is connected to the top mini-SAS

port on Unit 2.

• The bottom mini-SAS port on Unit 2 is connected to the top mini-SAS

port on Unit 3.

• The bottom mini-SAS port on Unit 3 is connected to the top mini-SAS

port on Unit 1.

Getting Started Guide 19

Stacking Standby

The stacking feature supports a Standby or backup unit that assumes the

Master unit role if the Master unit in the stack fails. As soon as a Master

failure is detected in the stack, the Standby unit initializes the control plane

and enables all other stack units with the current configuration. The Standby

unit maintains a synchronized copy of the running configuration for the

stack. The Standby unit is automatically selected in the stack; however, you

can use the CLI to select a different stack member as Standby. See the User’s

Configuration Guide or the CLI Reference Guide for more information.

Getting Started Guide 21

Connecting a N20xx Switch to a Terminal

After completing all external connections, connect a terminal to a switch to

configure the switch.

NOTE: Read the Release Notes for this product before proceeding. You can

download the Release Notes from the Dell Support website at

dell.com/support/manuals.

NOTE: We recommend that you obtain the most recent version of the user

documentation from the Dell Support website at dell.com/support/manuals.

To monitor and configure the switch via serial console, use the console port

on the front panel of the switch (see Figure 1-1 on page 8) to connect it to a

VT100 terminal or to a computer running VT100 terminal emulation

software. The console port is implemented as a data terminal equipment

(DTE) connector.

The following equipment is required to use the console port:

• VT100-compatible terminal or a computer with a serial port running

VT100 terminal emulation software,

such as Microsoft HyperTerminal.

• A serial cable (provided) with an RJ-45 connector for the console port and

DB-9 connector for the terminal.

Perform the following tasks to connect a terminal to the switch console port:

Connect the DB-9 connector on the serial cable to the terminal or

computer running VT100 terminal emulation software.

Configure the terminal emulation software as follows:

Select the appropriate serial port (for example, COM 1) to connect to

the console.

Set the data rate to 9600 baud.

Set the data format to 8 data bits, 1 stop bit, and no parity.

Set the flow control to none.

Set the terminal emulation mode to

VT100

Select Terminal keys for Function, Arrow, and Ctrl keys. Make sure

that the setting is for Terminal keys (not Microsoft Windows keys).

22 Getting Started Guide

Connect the RJ-45 connector on the cable directly to the switch console

port. The Dell Networking console port is located on the right side of the

front panel and is labeled with a

|O|O|

symbol, as shown in Figure 1-10

on page 22.

NOTE: Serial console access to the stack manager is available from any

serial port via the local CLI. Only one serial console session at a time is

supported.

Figure 1-10. N2024P Front Panel with Console Port

Connecting a N20xx Switch to a Power Source

CAUTION: Read the safety information in the Safety and Regulatory Information

manual as well as the safety information for other switches that connect to or

support the switch.

All N20xx models have one internal power supply. The

power receptacles are

on the back panel.

AC and DC Power Connection

Make sure that the switch console port is connected to a VT100 terminal

or VT100 terminal emulator via the RJ-45 to DB-9 female cable.

Using a 5-foot (1.5 m) standard power cable with safety ground connected,

connect the power cable to the AC main receptacle located on the back

panel (see Figure 1-11 on page 23).

Connect the power cable to a grounded AC outlet.

Console Port

Getting Started Guide 23

If you are using a redundant or external DC power supply, such as the Dell

Networking RPS720 or Dell Networking MPS1000, connect the DC power

cable to the DC receptacle located on the back panel. In Figure 1-11 on

page 23, the redundant power supply feed is in the middle and is labeled

RPS.

Figure 1-11. AC and DC Power Connection to an N2048 Switch

Booting the N20xx Switch

When the power is turned on with the local terminal already connected, the

switch goes through a power-on self-test (POST). POST runs every time the

switch is initialized and checks hardware components to determine if the

switch is fully operational before completely booting. If POST detects a

critical problem, the program flow stops. If POST passes successfully, valid

firmware is loaded into RAM. POST messages are displayed on the terminal

and indicate test success or failure. The boot process runs for approximately

60 seconds.

You can invoke the Boot menu after the first part of the POST is completed.

From the Boot menu, you can perform configuration tasks such as resetting

the system to factory defaults, activating the backup image, or recovering a

password. For more information about the Boot menu functions, see the CLI

Reference Guide.

To AC Power Source

24 Getting Started Guide

Performing the N20xx Initial Configuration

The initial configuration procedure is based on the following assumptions:

• The Dell Networking switch was never configured before.

• The Dell Networking switch booted successfully.

• The console connection was established, and the

Dell Easy Setup Wizard

prompt appears on the screen of a VT100 terminal or terminal equivalent.

The initial switch configuration is performed through the console port. After

the initial configuration, you can manage the switch from the already-

connected console port or remotely through an interface defined during the

initial configuration.

NOTE: The switch is not configured with a default user name, password, or IP

address.

Before setting up the initial configuration of the switch, obtain the following

information from your network administrator:

• The IP address to be assigned to the management interface.

• The IP subnet mask for the network.

• The IP address of the management interface default gateway.

These settings are necessary to allow the remote management of the switch

through Telnet (Telnet client) or HTTP (Web browser).

Enabling Remote Management

On the N20xx switches, you can use any of the switch ports on the front panel

for in-band management. By default, all in-band ports are members of VLAN

The Dell Easy Setup Wizard includes prompts to configure network

information for the VLAN 1 interface on the N20xx switch. You can assign a

static IP address and subnet mask or enable DHCP and allow a network

DHCP server to assign the information.

See the CLI Reference Guide for information about the CLI commands you

use to configure network information.

Getting Started Guide 25

Initial Configuration Procedure

You can perform the initial configuration by using the Dell Easy Setup

Wizard or by using the CLI. The wizard automatically starts when the switch

configuration file is empty. You can exit the wizard at any point by entering

[ctrl+z], but all configuration settings specified will be discarded, and the

switch will use the default values.

NOTE: If you do not run the Dell Easy Setup Wizard or do not respond to the initial

Easy Setup Wizard prompt within 60 seconds, the switch enters CLI mode. You must

reset the switch with an empty startup configuration in order to rerun the Dell Easy

Setup Wizard.

For more information about performing the initial configuration by using the

CLI, see the CLI Reference Guide. This Getting Started Guide shows how to

use the Dell Easy Setup Wizard for initial switch configuration. The wizard

sets up the following configuration on the switch:

• Establishes the initial privileged user account with a valid password. The

wizard configures one privileged user account during the setup.

• Enables CLI login and HTTP access to use the local authentication setting

only.

• Sets up the IP address for the VLAN 1 routing interface, of which all

in-band ports are members.

• Sets up the SNMP community string to be used by the SNMP manager at

a given IP address. You may choose to skip this step if SNMP management

is not used for this switch.

• Allows you to specify the network management system IP address or

permit management access from all IP addresses.

• Configures the default gateway IP address for the VLAN 1 interface.

26 Getting Started Guide

Applying Global configuration, please wait...

Welcome to Dell Easy Setup Wizard

The Setup Wizard guides you through the initial switch

configuration, and gets you up and running as quickly

as possible. You can skip the setup wizard, and enter

CLI mode to manually configure the switch. You must

respond to the next question to run the setup wizard

within 60 seconds, otherwise the system will continue

with normal operation using the default system

configuration. Note: You can exit the setup wizard at

any point by entering [ctrl+z].

Would you like to run the setup wizard (you must

answer this question within 60 seconds)? [Y/N] y

Step 1:

The system is not set up for SNMP management by

default. To manage the switch using SNMP (required for

Dell Network Manager) you can

. Set up the initial SNMP version 2 account now.

. Return later and set up other SNMP accounts. (For

more information on setting up an SNMP version 1 or

3 account, see the user documentation).

Would you like to set up the SNMP management interface

now? [Y/N] y

To set up the SNMP management account you must specify

the management system IP address and the “community

string” or password that the particular management

system uses to access the switch. The wizard

28 Getting Started Guide

automatically assigns the highest access level

[Privilege Level 15] to this account. You can use Dell

Network Manager or other management interfaces to

change this setting, and to add additional management

system information later. For more information on

adding management systems, see the user documentation.

To add a management station:

Please enter the SNMP community string to be used.

[public]: public

NOTE: If it is configured, the default access level is set to the highest available

access for the SNMP management interface. Initially only SNMPv2 will be

activated. SNMPv3 is disabled until you return to configure security access for

SNMPv3 (e.g. engine ID, view, etc.).

Please enter the IP address of the Management System

(A.B.C.D) or wildcard (0.0.0.0) to manage from any

Management Station. [0.0.0.0]: 10.1.2.100

Step 2:

Now we need to set up your initial privilege (Level

15) user account. This account is used to login to the

CLI and Web interface. You may set up other accounts

and change privilege levels later. For more

information on setting up user accounts and changing

privilege levels, see the user documentation.

To set up a user account:

Please enter the user name. [root]:admin

Please enter the user password: ********

Please reenter the user password: ********

Step 3:

Next, an IP address is set up on the VLAN 1 routing

interface.

You can use the IP address to access the CLI, Web

interface, or SNMP interface of the switch.

Getting Started Guide 29

To access the switch through any Management Interface

you can

. Set up the IP address for the Management Interface.

. Set up the default gateway if IP address is

manually configured on the routing interface.

Step 4:

Would you like to set up the VLAN1 routing interface

now? [Y/N] y

Please enter the IP address of the device (A.B.C.D) or

enter “DHCP” (without the quotes) to automatically

request an IP address from the network DHCP server:

10.1.1.200

Please enter the IP subnet mask (A.B.C.D or /nn):

255.255.255.0

Step 5:

Finally, set up the default gateway. Please enter the

IP address of the gateway from which this network is

reachable. [0.0.0.0]: 10.1.1.1

This is the configuration information that has been

collected:

SNMP Interface = “public”@10.1.2.100

User Account setup = admin

Password = ********

VLAN1 Router Interface IP = 10.1.1.200 255.255.255.0

Default Gateway = 10.1.1.1

Step 6:

If the information is correct, please enter (Y) to

save the configuration and copy the settings to the

start-up configuration file. If the information is

incorrect, enter (N) to discard the configuration and

restart the wizard: [Y/N] y

Thank you for using the Dell Easy Setup Wizard. You

will now enter CLI mode.

Next Steps

After completing the initial configuration described in this section, you can

connect any of the front-panel switch ports to your production network for in-

band remote management.

If you specified DHCP for the VLAN 1 management interface IP address, the

interface will acquire its IP address from a DHCP server on the network. To

discover the dynamically-assigned IP address, use the console port connection

to issue the following command:

• For the VLAN 1 routing interface, enter

show ip interface

To access the Dell OpenManage Switch Administrator interface, enter the

VLAN 1 management interface IP address into the address field of a Web

browser. For remote management access to the CLI, enter the VLAN 1

management interface IP address into a Telnet or SSH client. Alternatively,

you can continue to use the console port for local CLI access to the switch.

Your N20xx switch supports basic switching features such as VLANs and

spanning tree protocol. Use the Web-based management interface or the CLI

to configure the features your network requires. For information about how to

configure the switch features, see the User’s Configuration Guide or CLI

Reference Guide available on the support site: dell.com/support/manuals.

The N3024/N3024P front panel provides 24 Gigabit Ethernet

(10/100/1000BASE-T) RJ-45 ports that support auto-negotiation for speed,

flow control, and duplex. The N3024/N3024P models support two SFP+ 10G

ports. Dell-qualified SFP+ transceivers are sold separately.

The N3024F front panel provides 24 Gigabit Ethernet 100BASE-

FX/1000BASE-X SFP ports plus 2 1000BASE-T combo ports. Dell-qualified

SFP transceivers are sold separately.

The N3048/N3048P front panel provides 48 Gigabit Ethernet (10BASE-T,

100BASE-TX, 1000BASE-T) RJ-45 ports that support auto-negotiation for

speed, flow control, and duplex. The N3048/N3048P support two SFP+ 10G

ports. Dell-qualified SFP+ transceivers are sold separately.

The front-panel switch ports have the following characteristics:

• The switch automatically detects the difference between crossed and

straight-through cables on RJ-45 ports and automatically chooses the MDI

or MDIX configuration to match the other end.

• SFP ports support Dell-qualified transceivers.

• RJ-45 ports support full-duplex mode 10/100/1000 Mbps speeds on

standard Category 5 UTP cable.

• SFP+ ports support SFP+ transceivers and SFP+ copper twin-ax

technology plus SFP transceivers operating at 1G.

• The N3024P/N3048P front panel ports support PoE (15.4W) and PoE+

(30W).

Console Port

The console port provides serial communication capabilities, which allows

communication using RS-232 protocol. The serial port provides a direct

connection to the switch and allows access to the CLI from a console

terminal connected to the port through the provided serial cable (with RJ45

YOST to female DB-9 connectors).

The console port is separately configurable and can be run as an asynchronous

link from 1200 baud to 115,200 baud.

The Dell CLI only supports changing the speed.

Getting Started Guide 35

The defaults are 9600 baud rate, 8 data bits, No Parity, 1 Stop Bit, No Flow

Control.

Out-of-Band Management Port

The Out-of-Band (OOB) management port is a 10/100/1000BASE-T

Ethernet port dedicated to remote switch management. Traffic on this port is

segregated from operational network traffic on the switch ports and cannot be

switched or routed to or from the operational network.

USB Port

The Type-A, female USB port supports a USB 2.0-compliant flash memory

drive. The Dell Networking switch can read or write to a flash drive formatted

as FAT-32. You can use a USB flash drive to copy switch configuration files

and images between the USB flash drive and the switch. You can also use the

USB flash drive to move and copy configuration files and images from one

switch to other switches in the network.

The USB port does not support any other type of USB device.

Reset Button

The reset button is accessed through the pinhole and allows you to perform a

hard reset on the switch. To use the reset button, insert an unbent paper clip

or similar tool into the pinhole. When the switch completes the boot process

after the reset, it resumes operation with the most recently saved

configuration. Any changes made to the running configuration that were not

saved to the startup configuration prior to the reset are lost.

Port and System LEDs

The front panel contains light emitting diodes (LEDs) that indicate the

status of port links, power supplies, fans, stacking, and the overall system

status.

For information about the status that the LEDs indicate, see the User’s

Configuration Guide.

36 Getting Started Guide

Stack Master LED and Stack Number Display

When a switch within a stack is the master unit, the stack master LED, which

is labeled M, is solid green. If the M LED is off, the stack member is not the

master unit. The Stack No. panel displays the unit number for the stack

member. If a switch is not part of a stack (in other words, it is a stack of one

switch), the M LED is illuminated, and the unit number is displayed.

Power Supplies

N3024, N3024F and N3048

N3024, N3024F and N3048 switches support two 200-watt Field Replaceable

Unit (FRU) power supplies which give full power redundancy for the switch.

The N3024, N3024F and N3048 switches offer the V-lock feature for users

desiring the need to eliminate accidental power disconnection. The V-lock

receptacle on the

Power Supply Unit (

PSU) allows for the use of a power cord

that has the V-lock feature to create an integral secure locking connection.

N3024P and N3048P

Dell Networking N3024P and N3048P switches support one or two 1100-watt

FRU power supplies. The N3024P switch comes with a single 715-watt power

supply (the default configuration), and supports either one or two 1100-watt

supplies. For the N3048P switch, an 1100-watt power supply is the default

configuration.

A single 1100-watt power supply can feed up to 24 PoE devices at full PoE+

power (950W). Dual-equipped switches will feed up to 48 PoE devices at full

PoE+ power (1800W), as well as provide power supply redundancy.

NOTE: PoE power is dynamically allocated. Not all ports will require the full PoE+

power.

CAUTION: Remove the power cable from the power supplies prior to removing

the power supply module itself. Power must not be connected prior to insertion in

the chassis.

Ventilation System

Two fans cool the N30xx switches. The N30xx switches additionally have a

fan in each internal power supply. The N30xx fan is a FRU.

Place the container on a clean, flat surface and cut all straps securing the

container.

Open the container or remove the container top.

Carefully remove the switch from the container and place it on a secure

and clean surface.

Remove all packing material.

Inspect the product and accessories for damage.

42 Getting Started Guide

Rack Mounting a N30xx Switch

You may either place the switch on the rack shelf or mount the switch directly

into a 19" wide, EIA-310-E compliant rack (four-post, two-post, or threaded

methods). The Dell ReadyRail system is provided for 1U front-rack, and two-

post installations. The ReadyRail system includes two separately packaged rail

assemblies.

WARNING: This is a condensed reference. Read the safety instructions in your

Safety, Environmental, and Regulatory information booklet before you begin.

NOTE: The illustrations in this document are not intended to represent a specific

switch.

Rack Mounting Safety Considerations

• Rack loading—Overloading or uneven loading of racks may result in shelf

or rack failure, causing damage to equipment and possible personal injury.

Stabilize racks in a permanent location before loading begins. Mount

components beginning at the bottom of the rack, then work to the top. Do

not exceed your rack load rating.

• Power considerations—Connect only to the power source specified on the

unit. When multiple electrical components are installed in a rack, ensure

that the total component power ratings do not exceed circuit capabilities.

Overloaded power sources and extension cords present fire and shock

hazards.

• Elevated ambient temperature—If installed in a closed rack assembly, the

operating temperature of the rack environment may be greater than room

ambient. Use care not to exceed the 45 degrees C maximum ambient

temperature of the switch.

• Reduced air flow—Install the equipment in the rack so that the amount of

airflow required for safe operation of the equipment is not compromised.

• Reliable earthing—Maintain reliable earthing of rack-mounted

equipment. Pay particular attention to supply connections other than

direct connections to the branch circuit, for example: use of power strips.

• Product should not be mounted with the rear panel facing in the

downward position.

Getting Started Guide 43

Installing the Dell ReadyRail System

The ReadyRail rack mounting system is provided to easily configure your rack

for installation of your switch. The ReadyRail system can be installed using

the 1U tool-less method or one of three possible 1U tooled methods (two-

post flush mount, two-post center mount, or four-post threaded).

1U Tool-less Configuration (Four-post Square Hole or Unthreaded Round Hole)

With the ReadyRail flange ears facing outward, place one rail between the

left and right vertical posts. Align and seat the rear flange rail pegs in the

rear vertical post flange. In Figure 1-19, item 1 and its extractions illustrate

how the pegs appear in both the square and unthreaded round holes.

Figure 1-19. 1U Tool-less Configuration

Align and seat the front flange pegs in the holes on the front side of the

vertical post. See Figure 1-19, item 2.

Repeat this procedure for the second rail.

To remove each rail, pull on the latch release button on each flange ear and

unseat each rail. See Figure 1-19, item 3.

44 Getting Started Guide

Two-post Flush-mount Configuration

For this configuration, the castings must be removed from the front side of

each ReadyRail assembly. See Figure 1-20, item 1 on page 44. Use a Torx

driver to remove the two screws from each front flange ear (on the switch

side of the rail) and remove each casting. Retain the castings for future

rack requirements. It is not necessary to remove the rear flange castings.

Figure 1-20. Two-post Flush-mount Configuration

Attach one rail to the front post flange with two user-supplied screws. See

Figure 1-20, item 2.

Getting Started Guide 45

Slide the plunger bracket forward against the vertical post and secure the

plunger bracket to the post flange with two user-supplied screws. See

Figure 1-20, item 3.

Repeat this procedure for the second rail.

Two-post Center-mount Configuration

Slide the plunger bracket rearward until it clicks into place and secure the

bracket to the front post flange with two user-supplied screws. See

Figure 1-21, item 1.

Figure 1-21. Two-post Center-mount Configuration

Slide the back bracket towards the post and secure it to the post flange

with two user-supplied screws. See Figure 1-21, item 2.

Repeat this procedure for the second rail.

46 Getting Started Guide

Four-post Threaded Configuration

For this configuration, the flange ear castings must be removed from each

end of the ReadyRail assemblies. Use a Torx driver to remove the two

screws from each flange ear and remove each casting. See Figure 1-22, item

1. Retain the castings for future rack requirements.

For each rail, attach the front and rear flanges to the post flanges with two

user-supplied screws at each end. See Figure 1-22, item 2.

Figure 1-22. Four-post Threaded Configuration

Getting Started Guide 47

Installing as a Free-standing Switch

NOTE: We strongly recommend mounting the switch in a rack.

Install the switch on a flat surface if you are not installing it in a rack. The

surface must be able to support the weight of the switch and the switch

cables. The switch is supplied with four self-adhesive rubber pads.

Attach the self-adhesive rubber pads on each location marked on the

bottom of the switch.

Set the switch on a flat surface, and make sure that it has proper

ventilation by leaving 5 cm (2 inches) on each side and 13 cm (5 inches) at

the back.

Stacking Multiple N30xx Switches

You can stack N30xx switches up to 12 switches high using the mini-SAS

ports located on the rear of the switch. N30xx switches only support stacking

with other N30xx switches. When multiple switches are connected together

through the stack ports, they operate as a single unit with up to 576 front

panel ports. The stack operates and is managed as a single entity.

NOTE: If you are installing a stack of switches, you need to assemble and cable the

stack before powering up and configuring it. When a stack is powered up for the

first time, the switches elect a Master Switch, which may occupy any location in

the stack. The Master LED on the front panel is illuminated on the master unit.

Creating a Switch Stack

Create a stack by connecting adjacent units using the mini-SAS stacking

ports on the back panel of the switch. Figure 1-23 on page 48 shows the

switches connected in a ring topology, which is the recommended topology

for a stack.

Connect one of the mini-SAS cables into either of the stacking ports of the

top switch and the switch directly below it.

If necessary, use a separately purchased, longer (1 meter or 3 meter) mini-

SAS cable to connect the switches.

Repeat this process until all of the devices are connected.

Use the remaining stacking cable to connect the two remaining stacking

ports together so that a ring topology is assembled.

48 Getting Started Guide

Figure 1-23. Connecting a Stack of Switches

The stack in Figure 1-23 is connected in a ring topology and has the following
